Improvement in harvesters

GEORGE W. N. YOST, OF COREY, PENNSYLVANIA.

IM PROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 88,254, dated March 23, 1869.

To all interested:

I, GEORGE W. N. Yosr, of Corry, Pennsylvania, have invented a Climax Floating-Bar Fastening, an improvement of my climax floating bar for grass and grain cutters.

The following description and accompanyin g drawings, having like letters of reference, fully illustrate the invention.

A and A are my climax body, as described in my patent of August 18, 1868. S is my climax floating bar, as described in my patent of October 6, 1868. R is a cylinder projecting from each end of the body A and A, about four inches in diameter and length. g is a groove in the cylinder R at either or both ends of the body A and A. R is a band or loop, large enough to go over a cylinder, R, rigidly at tached to each end of the floating bar S. S is a key, adapted to the groove 9 of the cylinder R of the body A and A, made by projecting an end of the bar S through and within a loop, R, of the floating bar.

The invention is made by putting the loops R of the floating bar S, surrounding a traveling wheel, B, over the cylinders R of the body A and A, with the end of the bar, being the key S, within the groove g. The office of the key S is to make the attachment of the floating bar S to the body A and A rigid.

The floating bar, comprising the bar S and the loops R, and the key or keys S, made of two or more pieces, practically is one solid instrument or device, but the bar S may be one solid piece, with one or both the loops R attached at the laps l and l with screw-bolts; or the bar S may be in two pieces, fastened together at the corner m by screw-bolts, with one or both the loops R solidly bolted or welded to it at the laps l and l.

The nature of the invention is in making the bar S and the key S out of one piece of material, making an end of the floating bar itself constitute a key, instead of making a separate key.

Formerly I made a double groove or two grooves, g, part or one in the cylinder R, and the other in the inside of a loop, R, and made a separate small key, S, to fit therein, and held it in by a set-screw, 0; but the separate key had to be driven very tightly to be efl'ective, and then it was difficult to remove when desired. By making it of an end of the floating bar itself a better and stouter key is got at less cost, and one more easily put in or taken out.

I claim- Only the combination of a bar, S, projecting through and within a loop, R, of the floating bar, with a cylinder, R, of the body A and A, provided with a groove, g, and having the end of the bar S within said cylinder R in said groove 9, when made and used as described for grass and grain cutting machines.
